Working Principles

The SN74ABT8952DLR is designed to shift logic levels between two different voltage domains. It utilizes a combination of MOSFETs and CMOS technology to achieve bidirectional data transfer. The inputs and outputs are protected against electrostatic discharge (ESD) and latch-up events.

When the output enable (OE) signal is high, the device is enabled, and the input signals are transferred to the corresponding output pins. When the OE signal is low, the outputs are disabled, and the device enters a high-impedance state.
